    @brief   DAC HAL module driver.
            This file provides firmware functions to manage the following
            functionalities of DAC extension peripheral:
              + Extended features functions

                      ##### How to use this driver #####
    ==============================================================================
    [..]
      (+) When Dual mode is enabled (i.e DAC Channel1 and Channel2 are used simultaneously) :
          Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
          HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in Channel 1 and Channel 2.
      (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
      (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
